The information processing system 50 provides various services to the electronic device 10, the second terminal device 30 and the like through the network N1. The services vary depending on type of the electronic device 10. In the case of the image forming apparatus 10 a, the services include uploading and saving a scanned document to the storage on the cloud and downloading and printing image data of the storage on the cloud, but the service are not limited to the services described here. In the case of the electronic whiteboard 10 b, for example, the services include recognizing voice in real time and creating minutes, converting handwritten data into text, and the like. In the case of the second terminal device 30, for example, the services include a real-time translation service for web pages.

In the information processing system 50, a tenant and the user are associated with each other. The services (applications) that can be used are determined for each user, and the user uses the application that the user can use from the electronic device 10 or the first terminal device 20. In addition, tenants, administrators, and users have the following relationships. One customer has one tenant. In this case, the administrator and the user belong to one tenant. One customer has multiple tenants. In this case, the administrators do not necessarily belong to the tenants, but manage the users belonging to each tenant. The users belong to one or more tenants. In either case, the user registered in the information processing system 50 belongs to any of the tenants, so if the user is identified after registration, the tenant to which the user belongs is also identified.

The information processing system 50 creates screen information of a web page to be displayed on the first terminal device 20, the second terminal device 30, or the electronic device 10, and transmits the screen information to the first terminal device 20, the second terminal device 30, or the electronic device 10.

The browser information storage unit 36 is built in, for example, the HD 504 or the like, and is a non-volatile memory in which information is not deleted even when the web browser 31 is terminated. As a storage area in the terminal that can be managed by the web browser, a function called Local Storage implemented by HTML5 can be used.

FIG. 5 illustrates functions of the image forming apparatus 10 a as an example of the electronic device 10, but the functions described in the present embodiment are the same in the other electronic device 10, except for the function implemented by difference in the hardware.

The electronic device 10 includes functions executed by the control panel 940 and functions executed by a main body 44. The main body 44 is a part of the electronic device 10 illustrated in FIG. 4 other than the control panel 940. This is because the control panel 940 and the main body 44 each have an independent information processing function, which is implemented by a CPU or the like that is independent from each other. The control panel 940 implements a part of functions illustrated in a functional block as illustrated in FIG. 5 by executing a program (for example, web browser 11) or a dedicated application. The functions of the main body 44 illustrated in FIG. 5 is implemented by executing the program.

The functions executed by the control panel 940 are a third communication unit 12, a display control unit 13, an operation reception unit 14, a processing control unit 15, a web application 18, a native application 41, an IC card communication unit 42 and an authentication processing unit 43. The functions executed by the main body 44 are a main body authentication unit 45 and a web Application Programming Interface (API) 46.

The third communication unit 12 communicates with the information processing system 50 and receives screen information for the electronic device 10 to display a standby screen, the login screen, an application screen, and the like. In addition, the information input by the user on the standby screen, login screen, and application screen is transmitted to the information processing system 50.

The display control unit 13 analyzes the screen information of the screen received from the information processing system 50 and displays, for example, the standby screen, the login screen, and the application screen on the control panel 940. The operation reception unit 14 accepts user operations (for example, input of account information, selection of an application, operation on an application, etc.) on the electronic device 10.

The processing control unit 15 performs common processing for the electronic device 10 that provides a solution to the user by using a service such as device registration or login in the information processing system 50. When the authentication setting of the electronic device 10 is system authentication, the processing control unit 15 operates as a system authentication application and returns the authentication result from the information processing system 50 to the main body authentication unit 45. The authentication ticket issued by the information processing system 50 to the user's account is shared by each application of the electronic device 10. The system authentication is the main body custom authentication in the cloud. A custom authentication application is added to the control panel 940, and the custom authentication application refers to an authentication method in which the cloud and authentication information are transmitted, and results are acquired. For example, the authentication is entrusted to a custom authentication application such as the authentication processing unit 43. Note that system authentication refers to authentication performed after the control panel 940 is started and before each application on the control panel 940 is used, as opposed to authentication for each application (custom authentication at the time of starting the application).

When the authentication setting of the electronic device 10 is not the system authentication, the processing control unit 15 receives a device registration or login request from an application that provides a solution using a service on the information processing system 50 and performs the processing request to the information processing system 50 on behalf of the information processing system 50, while displaying the screen. Results are returned only to the requested application. In the present embodiment, the case of system authentication is mainly described.

Since the screen displayed by the processing control unit 15 and the screen displayed by the web application 18 must be the same when the native application 41 requests device registration or login (for the same function), the WebView function of ANDROID (registered trademark) is used to implement the browser function and display the common screen with the web application 18 in the present embodiment.

The web application 18 is an application displayed and executed on the web browser on the control panel 940 of the electronic device 10. In order to provide a solution by using the service on the information processing system 50 as in the native application 41 described below, it is necessary to implement a device registration and login function in the information processing system 50.

The native application 41 is an application executed on the operating system (OS) running on the control panel 940 of the electronic device 10. When the native application 41 is started, the device registration status is acquired from the processing control unit 15. If the device is not registered, a registration request is transmitted to the processing control unit 15. The user executes device registration using the displayed registration screen. Even when it is necessary to log in to the information processing system 50, the native application 41 can use the processing control unit 15 to display a common authentication screen and receive the authentication result.

The IC card communication unit 42 receives information from the short-range communication circuit 920 and sends the information to the processing control unit 15. Specifically, an IC card number is received from the short-range communication circuit 920 and sent to the processing control unit 15. The IC card communication unit 42 is created according to the type of the short-range communication circuit 920 and the IC card.

The authentication processing unit 43 performs authentication processing in the system on the control panel 940 side according to the instruction of the processing control unit 15. In the present embodiment, the authentication result is notified to the main body authentication unit 45.

The main body 44 includes the web API 46 and the main body authentication unit 45. The web API 46 is an interface on the main body 44 that allows the control panel 940 to acquire settings of the main body 44 of the electronic device 10 and execute functions. Such an API is called a remote I/F. When the device is registered in the information processing system 50, the native application 41 or the web application 18 acquires the machine number of the electronic device 10 by using the web API 46.

The main body authentication unit 45 is an authentication service on the main body. When the authentication setting of the electronic device 10 is the system authentication, the main body authentication unit 45 receives the authentication result from the information processing system 50 through the control panel 940.

TABLE 1 Authentication Method Flag A User ID userId B E-mail Address email C User Selection userselect D PIN Code pincode E IC Card iccard F All all

The authentication method as illustrated in Table 1 is stored in the browser information storage unit 16 of the electronic device 10. Table 1 illustrates examples of the authentication methods stored in the browser information storage unit 16. The authentication methods (A) to (F) are indicated in Table 1, together with flags that identify respective authentication methods. The processing control unit 15 identifies the stored authentication method by reading the flag.

For example, when the flag is “userId”, the electronic device 10 displays a login screen corresponding to the authentication method using the user ID. When the flag is “email”, the electronic device 10 displays a login screen corresponding to the authentication method using the e-mail address. When the flag is “userselect”, the electronic device 10 displays a login screen corresponding to the authentication method by user selection. When the flag is “pincode”, the electronic device 10 displays a login screen corresponding to the PIN code authentication method. When the flag is “iccard”, the electronic device 10 displays a login screen corresponding to the authentication method using the IC card. When the flag is “all”, the first terminal device 20 displays a login screen corresponding to all authentication methods.

The values of the flags in Table 1 indicate that the authentication methods are all “ON (valid)”. The value indicating “OFF (invalid)” may be, for example, NULL or a blank. As described below, the electronic device 10 receives a set value from the information processing system 50 and sets the flag corresponding to the set value. In addition, the administrator can set the flag for each electronic device 10.

The information processing system 50 includes a fourth communication unit 52, a screen information generation unit 53, a user information management unit 54, a tenant information management unit 55, an authentication permission unit 56, a device setting management unit 61, and device management unit 63. These functions of the information processing system 50 are functions implemented by the CPU 501 of the computer 500 illustrated in FIG. 3 executing a program developed from the HD 504 to the RAM 503.

The fourth communication unit 52 transmits and receives various information to and from the first terminal device 20, the second terminal device 30, and the electronic device 10. For example, the screen information of the login screen is transmitted to the second terminal device 30, and the account information is received from the second terminal device 30. Further, the screen information of the standby screen, the login screen, a top screen (portal screen), and the application screen is transmitted to the electronic device 10. In addition, the information entered on these screens are received.

The screen information generation unit 53 generates screen information of various screens displayed by the first terminal device 20, the second terminal device 30, and the electronic device 10, and transmits to the first terminal device 20, the second terminal device 30, and the electronic device 10 through the fourth communication unit 52.

The user information management unit 54 manages the generation, update, acquisition, and deletion of user information in the user information storage unit 57. The tenant information management unit 55 similarly manages the information of the tenant to which the user belongs in the tenant information storage unit 58. The user and the tenant are associated with each other by the user information and the tenant information.

The device management unit 63 accepts registration of the electronic device 10 such as the image forming apparatus 10 a and registers the electronic device 10 in the device information storage unit 64. The device setting management unit 61 receives a setting related to IC card login from the second terminal device 30 and stores the settings in the device setting information storage unit 62.

The authentication permission unit 56 authenticates the administrator or the user based on the account information and determines whether the authentication succeeds or fails. Authentication indicates determining whether or not a user is a legitimate authority. In the case of the present embodiment, the authentication determines whether the user or the administrator has the authority to use the information processing system 50, and the user or the administrator can also be distinguished. Authorization indicates determining the authority granted to a user according to a role of the user (described below). For example, the resources that can be accessed and the operations that can be performed are determined.

If the authentication is successful, the information processing system 50 allows the user to log in to the information processing system 50. A login is an authentication act to access system resources with pre-registered account information when using various services on a computer or the internet. The account information differs depending on the authentication methods (A) to (F) described above.

Further, the information processing system 50 includes a user information storage unit 57, a tenant information storage unit 58, a device setting information storage unit 62, and a device information storage unit 64 implemented by the HD 504, RAM 503, and the like illustrated in FIG. 3. The above described elements are described with reference to Tables 2 to 5.

TABLE 2 Parameter Description Example Tenant ID ID for Tenant which user tenant 1234 belongs User ID ID for user unique within user9876 tenant Password Password password Password flag Indicates whether password True is set Last name Last name of user Smith First name First name of user John E-mail address E-mail address of user john@example.com Display language Language used on English screens and e-mails Country Country which user belongs Japan Status Status of user's Valid account Time zone Time zone of user Asia/Tokyo Role Administrator or Administrator general user UUID Unique ID for user External service Information on the account External service ID: account information in the external service user 9999 linked by user List of available List of available service Service 1, service 2 service authority authority information information for user

Table 2 describes an example of user information stored in the user information storage unit 57. “Tenant ID” is identification information indicating the tenant to which the user belongs. “ID” is an abbreviation for “identifier,” and indicates an identification or identification information. ID is any one of a name, a symbol, a character string, a numerical value, or a combination of at least two of these items, which is used for identifying a particular object from among a plurality of objects. The same applies to IDs other than the tenant IDs. “User ID” is identification information that uniquely indicates a user within the tenant. Since the user ID is unique within a tenant, the user ID may be duplicated between different tenants. “Password” may be a part of account information. “Password flag” indicates that the password is set if “True” and not set if “False”. “Last name” is the surname (last name) of the user. “First name” is the first name of the user. “E-mail address” is the user's e-mail address. The e-mail addresses are unique worldwide and are duplicated between different tenants. For this reason, the e-mail address is often used as identification information for identifying a user. “Display language” is the written language when the terminal device displays various screens and e-mails. “Country” is the country or region to which the user belongs. “Status” is the status of the user's account. An account is a user's right to log in to the information processing system 50. There are at least three account statuses: “valid”, “invalid” or “account locked”. If user information is temporarily registered, the user information is invalid, and the user information becomes valid by full registration. The administrator can invalidate the user information even after the user information has been validated. Account lock is set when the user makes mistakes in entering a password several times. A locked account is different from an invalid account in that, for example, the locked account returns to a valid account after a period of time or remain counted as users belonging to the tenant. In addition, an invalid account may be due to expiration. “Time zone” is the time zone (Coordinated Universal Time (UTC)) of a country or region in which the user operates. “Role” indicates what kind of authority the account has. In the present embodiment, the role is an administrator, or a general user. When a general user and an administrator are not particularly distinguished, the general user and the administrator are referred to as users. “Universally Unique Identifier (UUID)) is identification information that uniquely indicates a user and is used when the information processing system 50 identifies the user. “External service account information” is information on the account in the external service 70 that the user has registered in cooperation with (identification information in the external service 70). “List of available service authority information” is a list of services available to the user.

TABLE 3 Parameter Description Example Tenant ID ID for Tenant which user tenant 1234 belongs Tenant name Name of tenant Test tenant Display Language used on screens English language and e-mails Country Country which user belongs Japan Status Status of user's account Valid Time zone Time zone of user Asia/Tokyo Login setting Authentication method permitted Login by e-mail address by tenant when logging into and password permitted web application

Table 3 describes an example of tenant information stored in the tenant information storage unit 58. “Tenant ID” is the same as in Table 2. “Tenant name” is the name of the tenant (the name called by the user). “Display language” is a language for displaying characters on the screens, e-mails, and the like. “Country” a country or region to which the tenant belongs. “Status” includes valid and invalid statuses of the tenant. Invalid status is a state in which the tenant cannot receive the service due to the termination of the contract. “Time zone” is the time zone (UTC) of the country or region where the tenant operates. “Login setting” is an authentication method permitted by the tenant when the user logs in to the information processing system 50 (refer to Table 5).

TABLE 4 Parameter Description Example Tenant ID ID for tenant who owns tenant 1234 electronic device Machine number ID for electronic device K001 . . . . . . . . .

Table 4 describes an example of device information stored in the device information storage unit 64. “Tenant ID” is the same as in Table 2. The tenant ID indicates the tenant that holds the device. “Machine number” is identification information of an electronic device for which an authentication method is set by the administrator. There are as many machine numbers as there are electronic devices 10 owned by the tenant.

TABLE 5 Parameter Description Example Default Tenant ID ID for tenant who owns tenant electronic device 1234 Set value for Set value indicating ON or OFF authentication whether to allow method using login by user ID user ID Set value for Set value indicating ON or OFF authentication whether to allow method using login by e-mail e-mail address address Set value for Set value indicating ON or OFF authentication whether to allow method using user login by user selection selection Set value for Set value indicating ON or OFF authentication whether to allow method using login by PIN code PIN code Set value for Set value indicating ON or OFF default authentication whether to allow method using login by IC card IC card Set value for all Set value indicating ON or OFF authentication whether to allow methods all login methods

Table 5 describes an example of the device setting value information stored in the device setting information storage unit 62. “Tenant ID” is the same as in Table 2. The tenant ID indicates the tenant that holds the device. “Set value for authentication method using the user ID” is a set value indicating whether to allow login by the user ID. “Set value for authentication method using the e-mail address” is a set value indicating whether to allow login by the e-mail address. “Set value for authentication method using the user selection” is a set value indicating whether to allow login by the user selection. “Set value for authentication method using the PIN code” is a set value indicating whether to allow login using the PIN code. “Set value for authentication method using the IC card” is a set value indicating whether to allow login using the IC card. “Set value of all authentication methods” is a set value indicating whether to allow all authentication methods.

The ON or OFF of the items in the example of Table 5 can be set by the administrator. For example, the set value of login by the IC card indicates whether the user can log in with the IC card (set value: ON) or not (set value: OFF).

The administrator can set the default authentication method. In Table 5, login by the IC card is set as the default.

FIG. 6 is a diagram illustrating an example of a device registration screen 200 displayed by the electronic device when the administrator registers the electronic device in the information processing system 50. The device registration screen 200 includes a message 201 “Please enter the tenant administrator information to register this device”, a login method field 202, a tenant ID field 203, a user ID field 204, a password field 205, and a registration button 206. The login method field 202 is a field for the administrator to select the login method for the electronic device. The following input fields are displayed according to the method selected in the login method field 202. When the authentication method is the “user ID”, the tenant ID, the user ID, and the password are required. In the tenant ID field 203, the tenant ID of the customer who owns the electronic device is input. In the user ID field 204, identification information assigned to the device (which may not be duplicated in the tenant) is input. In the password field 205, a password for authentication is input. The registration button 206 is a button for the electronic device 10 to send the account information input to the device registration screen to the information processing system 50. The electronic device 10 transmits the account information to the information processing system 50 together with the machine number. The account information is used for administrator authentication, and if the authentication is successful, the device management unit 63 registers the machine number and the tenant ID in the device information storage unit 64.

A login screen corresponding to the authentication method is described with reference to FIGS. 7 to 11. The authentication method and required account information are described. (A) For authentication by the user ID, a user ID, a tenant ID, and a password are required. (B) For authentication by the e-mail address, an e-mail address, and a password are required. (C) For authentication by the user selection, a user ID, a tenant ID, and a password are required. (D) For authentication by the PIN code, a PIN code (numbers, symbols, alphabets, or combinations thereof that have a certain number of unique digits) is required. (E) For authentication by the IC card, a card number stored in the IC card, etc. is required. In addition, the account information includes biometric authentication information such as fingerprints and faces. In this case, an authentication method corresponding to the biometric authentication information is prepared.

FIG. 7 illustrates an example of the login screen 210 displayed by the electronic device 10 when the authentication method is the user ID. The login screen 210 of FIG. 7 includes a user ID field 211, a password field 212, a tenant ID field 213, and a login button 214. The user inputs the user ID in the user ID field 211, the password in the password field 212, the tenant ID in the tenant ID field 213, and presses the login button 214. The operation reception unit 14 receives the operation, and the authentication processing unit 43 transmits the account information to the information processing system 50 through the third communication unit 12. Further, the authentication processing unit 43 receives the authentication result through the third communication unit 12 and notifies the main body authentication unit 45.

FIG. 8 illustrates an example of a login screen 220 displayed by the electronic device 10 when the authentication method is the e-mail address. The login screen 220 of FIG. 8 includes an e-mail address field 221, a password field 222, and a login button 223. The user inputs the e-mail address in the e-mail address field 221, the password in the password field 222, and presses the login button 223. The tenant ID is not required because the e-mail address is guaranteed to be unique worldwide (the user ID is guaranteed to be unique only within the tenant). The operation reception unit 14 receives the operation, and the authentication processing unit 43 transmits the account information to the information processing system 50 through the third communication unit 12. Further, the authentication processing unit 43 receives the authentication result through the third communication unit 12 and notifies the main body authentication unit 45.

FIG. 9 illustrates an example of the login screen 260 displayed by the electronic device 10 when the authentication method is the user selection. In other words, it is not necessary to enter the e-mail address, which improves convenience. The login screen 260 of FIG. 9 includes an e-mail address list 261. The e-mail address list 261 is displayed based on, for example, an employee's address book. The user selects the e-mail address of the user from the e-mail address list 261. In response to inputting the selection, the e-mail address list 261 switches to the password field. The user enters the password in the password field and presses the login button.

FIG. 10 illustrates an example of a login screen 230 displayed by the electronic device 10 when the authentication method is the PIN code. The login screen 230 of FIG. 10 includes a PIN code field 231 and a login button 232. The user inputs the PIN code in the PIN code field 231 and presses the login button 232. The operation reception unit 14 receives the operation, and the authentication processing unit 43 transmits the account information to the information processing system 50 through the third communication unit 12. Further, the authentication processing unit 43 receives the authentication result through the third communication unit 12 and notifies the main body authentication unit 45.

FIG. 11 illustrates an example of a login screen 240 displayed by the electronic device 10 when the authentication method is the IC card. On the login screen 240 of FIG. 11, a message 241 “Please hold the IC card over the reader to log in.” is displayed. When this screen is displayed, the short-range communication circuit 920 transmits a radio wave and starts searching for the IC card. When the IC card reaches the communication range, the IC card communication unit 42 receives the card number from the IC card. The authentication processing unit 43 transmits the account information to the information processing system 50 through the third communication unit 12. Further, the authentication processing unit 43 receives the authentication result through the third communication unit 12 and notifies the main body authentication unit 45.

An authentication method setting screen 250 set by the administrator is described with reference to FIG. 12. FIG. 12 is an example of the authentication method setting screen 250 displayed by the second terminal device 30. The administrator is logged in to the information processing system and the tenant ID is identified to display the authentication method setting screen 250.

The authentication method setting screen 250 is a screen for the administrator to set an authentication method for each electronic device 10. It is assumed that the authentication method setting screen 250 of FIG. 12 is common to all the electronic devices 10 owned by the tenant. However, the administrator may be able to set the authentication method for each electronic device 10. In this case, the administrator inputs the machine number before or after the display of the authentication method setting screen 250 of FIG. 12.

The authentication method setting screen includes an IC card login setting field 251, a PIN code login setting field 252, an external service link setting field 253, a user selection field 254, and a default authentication method setting field 255. The IC card login setting field 251 receives whether to validate or to invalidate the IC card login. The PIN code login setting field 252 received whether to validate or to invalidate the login by PIN code. Further, the number of digits of the PIN code is received in a number of digits column 256, and a generation method is received in a generation method column 257. The external service link setting field 253 receives whether to validate or to invalidate login by linking with an external service. The external service is, for example, a commercial or general-purpose cloud service that supports OAUTH, OPENID, and the like. GOOGLE (registered trademark), OFFICE365 (registered trademark), FACEBOOK (registered trademark), etc. are known. The user selection field 254 receives whether to validate or to invalidate login by selecting the user's e-mail address (FIG. 9) as the authentication method using the e-mail address. The default authentication method setting field 255 receives the default (initial setting) authentication method.

The content set by the administrator on the authentication method setting screen 250 is received by the fourth communication unit 52 of the information processing system 50, and the device setting management unit 61 stores the settings in the device setting information storage unit 62.

In FIG. 12, whether the login by the user ID is valid or invalid, and whether the login by the e-mail address is valid or invalid are not set. This is because these settings are validated in principle. However, these settings may also be set by the administrator in the same manner.

In addition, the administrator can confirm the tenant ID, tenant name, country information, time zone, and the like. Further, the authentication method for the authentication method setting screen 250 can be set by operating the second terminal device 30. The options are the e-mail address login, user ID, link with external services, or all of these. In addition, the administrator can display a list of licenses (applications) that can be used by the tenant by operating the second terminal device 30.

A process executed by the electronic device to display the login screens of FIGS. 7 to 11 is described with reference to FIG. 13. FIG. 13 is a sequence diagram illustrating an example of the process from when an authentication application is started until the login screen is displayed. The authentication processing unit 43 is implemented by the authentication application.

In step S1, the authentication processing unit 43 requests the main body of the electronic device 10 to acquire device configuration information. The device configuration information is information related to the configuration and functions of the electronic device 10. For example, color or monochrome, double-sided or single-sided, paper size, combined printing, staples, etc. The machine number is also included in the device configuration information.

In step S2, the web API 46 of the main body transmits the machine number to the authentication processing unit 43. Since the web API 46 is an interface, transmission by the web API 46 indicates that the authentication processing unit 43 calls the web API 46 to acquire or notify the information. In the present embodiment, “transmission by the web API 46” is used for the sake of simplicity.

In step S3, the authentication processing unit 43 requests the information processing system 50 to issue an authentication challenge for the electronic device 10 through the third communication unit 12. The authentication challenge is information used in an authentication method called challenge and response authentication.

In step S4, the fourth communication unit 52 of the information processing system 50 receives a request for issuing an authentication challenge, and the authentication permission unit 56 generates a different data string each time determined based on random numbers. This data string is called the authentication challenge. The fourth communication unit 52 transmits the authentication challenge to the electronic device 10.

In step S5, the third communication unit 12 of the electronic device 10 receives the authentication challenge, and the authentication processing unit 43 requests the main body 44 of the electronic device 10 to specify the authentication challenge and issue an authentication token.

In step S6, the main body authentication unit 45 of the main body of the electronic device 10 generates the authentication token. The main body authentication unit 45 converts the authentication challenge into a hash value by a hash function. In addition, the main body authentication unit 45 encrypts the hash value. The encrypted hash value is the authentication token. The authentication token is a one-time password. The main body authentication unit 45 also transmits information on the encryption type (Rivest Cipher 4 (RC4), Data Encryption Standard (DES), Triple Data Encryption Algorithm (3DES), Advanced Encryption Standard (AES), etc.) used at the time of creation.

In step S7, the authentication processing unit 43 requests the information processing system 50 to issue an authentication ticket by designating the authentication token through the third communication unit 12.

In step S8, the fourth communication unit 52 of the information processing system 50 receives the authentication ticket issuance request, and the authentication permission unit 56 verifies the authentication token. That is, the authentication challenge transmitted in step S4 is converted into a hash value, and whether the hash value matches the hash value transmitted from the electronic device 10 is determined. If the hash values match, it is determined that the electronic device 10 has been authenticated, and an authentication ticket that guarantees identity is issued to the electronic device 10. The fourth communication unit 52 transmits the authentication ticket to the electronic device 10.

In step S9, the third communication unit 12 of the electronic device 10 receives the authentication ticket, and the authentication processing unit 43 specifies the authentication ticket and the machine number to the information processing system 50 through the third communication unit 12 to obtain device information. The device information is information related to the device. In the present embodiment, the device information is not required, and an inquiry is made as to whether or not the electronic device 10 is registered.

When the electronic device is registered in the information processing system 50, steps S10 to S17 are executed.

In step S10, the fourth communication unit 52 of the information processing system 50 receives the request for device information, and the authentication permission unit 56 collates the issued authentication ticket with the received authentication ticket. If the authentication tickets match, the device management unit 63 acquires the device information specified by the machine number from the device information storage unit 64 and transmits the device information to the electronic device 10 through the fourth communication unit 52. In the present embodiment, it is assumed that the tenant ID is included in the device information.

In step S11, the third communication unit 12 of the electronic device 10 receives the device information. Since the electronic device 10 has already been registered, the authentication processing unit 43 requests a resource owner of OAUTH through the third communication unit 12 for authorization by designating the authentication ticket. Authorization is authority granted to electronic devices.

In step S12, the third communication unit 12 of the electronic device 10 receives a redirect uniform resource locator (URL) and an authorization code from the resource owner. The redirect URL is a URL for reconnecting to the information processing system 50. The authorization code is identification information indicating contents of authority.

In step S13, the third communication unit 12 of the electronic device 10 connects to the redirect URL, specifies an authorization code to the information processing system 50, and requests an access token. The access token determines an accessible data range identified by the authorization code.

In step S14, the fourth communication unit 52 of the information processing system 50 receives the request for the access token, and the authentication permission unit 56 transmits the access token determined by the authorization code to the electronic device 10.

In step S15, the third communication unit 12 of the electronic device 10 receives the access token, and the processing control unit 15 specifies the access token and the tenant ID to request tenant information. The tenant ID is included in the device information.

In step S16, the fourth communication unit 52 of the information processing system 50 receives the tenant information and the acquisition request of the set value, the tenant information management unit 55 acquires the tenant information from the tenant information storage unit 58, and the device setting management unit 61 acquires the set value from the device setting information storage unit 62. The set value may include all the information in Table 5. The fourth communication unit 52 transmits the tenant information and the set value to the electronic device 10.

In step S17, the third communication unit 12 of the electronic device 10 receives the tenant information and the set value, and the processing control unit 15 identifies the default authentication method from the permitted authentication methods. In the present embodiment, the default authentication method is the IC card. The display control unit 13 displays the login screen corresponding to the default authentication method on the display. The set value includes whether the IC card login is valid or invalid. When the default IC card login is valid, the display control unit 13 displays the login screen with the IC card. When the IC card login is invalid, the display control unit 13 displays the login screen according to permitted authentication methods (A) to (D). Which login screen to display may be decided in advance, or the last displayed login screen may be displayed.

Further, when the IC card login setting value acquired last time is “invalid” and the IC card login setting value acquired this time is “valid”, the processing control unit 15 validates the settings related to the IC card of the browser information storage unit 16 of the electronic device 10 (sets the iccard). That is, the set value of the browser information storage unit 16 of the electronic device 10 is changed according to the set value acquired this time. In this case, the electronic device 10 restarts as necessary. The IC card login setting value obtained last time is the value of the flag stored in the browser information storage unit 16.

On the contrary, when the IC card login setting value acquired last time is “valid” and the IC card login setting value acquired this time is “invalid”, the processing control unit 15 validates the setting related to the IC card of the browser information storage unit 16 of the electronic device 10 (NULL is set). In this case, the electronic device 10 restarts as necessary.

On the other hand, if the electronic device 10 is not registered in the information processing system 50, steps S18 and S19 are executed.

In step S18, the fourth communication unit 52 of the information processing system 50 transmits to the electronic device 10 that the electronic device 10 is not registered.

In step S19, the third communication unit 12 of the electronic device 10 receives that the electronic device 10 is not registered. The display control unit 13 displays a screen indicating that the electronic device 10 has not been registered. As a result, the administrator can register the electronic device 10 from the device registration screen 200 of FIG. 6.

FIG. 14 is a sequence diagram illustrating a process in which an information processing system 50 authenticates a user using account information input to the login screen.

Steps S21 to S23 may be the same as steps S15 to S17 in FIG. 12.

In step S24, the user inputs account information (user ID, password, etc.) according to the authentication method on the login screen. The operation reception unit 14 accepts the input of account information.

In step S25, the user presses the login button displayed on the login screen. The operation reception unit 14 receives pressing of the button.

In step S26, the authentication processing unit 43 requests login to the web API 46.

In step S27, the web API 46 transmits an external authentication request to the authentication processing unit 43. The external authentication request indicates requesting authentication from the information processing system 50.

One of steps S28 to S31 is executed depending on the authentication method.

In step S28, when the authentication method is the authentication by user ID, the authentication processing unit 43 transmits the tenant ID, the user ID, and the password to the information processing system 50 through the third communication unit 12.

In step S29, when the authentication method is the authentication by e-mail address, the authentication processing unit 43 transmits an e-mail address and a password to the information processing system 50 through the third communication unit 12.

In step S30, when the authentication method is the authentication by user selection, the authentication processing unit 43 transmits the tenant ID, the user ID, and the password to the information processing system 50 through the third communication unit 12.

In step S31, when the authentication method is the authentication by PIN code, the authentication processing unit 43 transmits the PIN code to the information processing system 50 through the third communication unit 12.

In step S32, when the authentication method is the authentication by IC card, the authentication processing unit 43 transmits a card number of the IC card to the information processing system 50 through the third communication unit 12.

If any of steps S28 to S32 is successful, the following steps S33 to S43 are executed.

In step S33, the authentication permission unit 56 of the information processing system 50 transmits an authentication success notice regarding the user and the user information (obtained from the user information storage unit 57) of the user identified by the success of the user authentication to the electronic device 10. The user information includes a user authentication ticket generated by authentication.

In step S34, the third communication unit 12 of the electronic device 10 receives the user information (including the user authentication ticket). The authentication processing unit 43 notifies web API 46 of the authentication success.

In step S35, the web API 46 notifies the main body 44 of the electronic device 10 that the login is successful. As a result, the control panel 940 can use the functions of the main body 44 (log in to the main body 44).

In step S36, the web API 46 notifies the authentication processing unit 43 of a login response (that a login success has been received).

In step S37, the web API 46 notifies the authentication processing unit 43 of the change in the state of the authentication service. The change of state of the authentication service indicates that the user is logged in.

In step S38, since the authentication processing unit 43 has logged in, the display control unit 13 closes the login screen.

In steps S39 to S43, the user registers in the information processing system 50, the registered name of the user who has successfully logged in on the address book of the main body 44 of the electronic device 10.

In step S39, the authentication processing unit 43 specifies the user authentication ticket to the information processing system 50 through the third communication unit 12 and requests the resource owner for authorization.

In step S40, the third communication unit 12 of the electronic device 10 receives a redirect URL and an authorization code from the resource owner.

In step S41, the third communication unit 12 of the electronic device 10 receives the redirect URL and the authorization code, and the authentication processing unit 43 connects to the redirect URL through the third communication unit 12 to obtain the access token specified by the authorization code.

In step S42, the fourth communication unit 52 of the information processing system 50 receives the request for the access token, and the authentication permission unit 56 transmits the access token based on the authorization code to the electronic device 10 through the fourth communication unit 52.

In step S43, the third communication unit 12 of the electronic device receives the access token, and the authentication processing unit 43 requests the information processing system 50 to update the information of the user through the third communication unit 12.

If the login in steps S28 to S32 fails, the following steps S44 to S48 are executed.

In step S44, the authentication permission unit 56 of the information processing system 50 notifies the electronic device 10 of the reason for failure (illegal request, authentication error, etc.) through the fourth communication unit 52.

In step S45, the third communication unit 12 of the electronic device receives the reason for failure, and the authentication processing unit 43 notifies the web API 46 that the authentication has failed.

In step S46, the web API 46 notifies the authentication processing unit 43 of a login response (that a login failure has been received).

In step S47, the web API 46 notifies the authentication processing unit 43 of the change of the login status.

In step S48, in response to a login failure notice, the display control unit 13 of the authentication processing unit 43 displays a login failure screen on the display.

If there is no response in any of steps S28 to S32 due to a communication error or the like, steps S49 to S50 are executed.

In step S49, the authentication processing unit 43 executes a timeout process because there is no response and determines that a communication error or a server error occurred.

In step S50, the display control unit 13 displays the login failure screen on the display.
